We need to provide customisable mappings between CKAN models and RDF. This needs to be easily configurable for different clients and should take into account objects related to the model being mapped.

Current contenders for impl are:

1. ordf.org's Object Description Mapper (which uses OWL)

2. RDFAlchemy, although this looks like it may result in fixed mappings

3. A custom scheme with a simple json file

4. A template based approach using Genshi templates?

Approach is to get a mapping complete of the attributes directly in the package class, and then provide mappings for related objects (tags/resources etc).

We'll then need to be able to publish the RDF to a triplestore.

See ​http://ckan.okfnpad.org/rdfmapping for further analysis.

It is necessary to add a helper method to Group for adding members to that group so that

• nobody needs to work with the Member model
• It handles existing membership and existing membership with a different capacity

Most of the get_group/add_member style calls should be handled, or at least provided via logic layer.

Don't need to break existing code, but do need to provide access via logic layer
